Dropshipping sites that are Mac compatible?

Hello, My husband and I joined about 2 weeks ago. I am a Mac user and we are trying to start this on a shoestring so am wanting to use drop shippers at least in the beginning. We are having difficulty being able to download the information such as pictures and especially descriptions from sites that we have signed up to use. Especially having difficulty with hotbuy4u.com. Are there any other Mac users out there that can give us tips, sites or etc. that are Mac compatible, to make this easier on us? Would certainly be most grateful for any help. Thank you Jean
